MACHINE FOR FASTENING HANGERS ON ELE CTRIC WIRE CABLES.

SPECIFICATION forming part of Letters Patent No. 583,411, dated May 25, 1897.

Application filed July 18, 1896. Serial No. 599,738. (No model.)

To all whom it may concern:

Be it known that we, \VILLBUR H. J OHN- STON, residing at St. Louis, in the State of Missouri, and SAMUEL B. FOWLER, residing at Chicago, in the county of Cook and State of Illinois, citizens of the United States, have invented certain new and useful Improvements in Machines for Fastening Hangers on Electrical Wire Cables, of which the following is a specification.

I-Ieretofore these hangers have been secured to the cable by means of a pair of tongs which bent a hanger, somewhat similar in shape to the one here used, but not provided with means for riveting, around the cable, and which hanger supported the cable by means of its stiffness alone, which, it is needless to say, was an insecure support.

The object, therefore, of our invention is to provide easier and more effective means for putting the hangers on the cable, and also means for securely holding said hangers in their proper position when put on, that they may perform their functions with very much lessened, if not wholly, without the contingency of allowing the weight of the cable to bend the hanger and slip-out of place. We attain these objects in a manner hereinafter fully described and claimed.

In the drawings, Figure 1 is a plan View of the improved machine for fastening the hangers onto the cable; Fig. 2, a side view of the same; Fig. 3, a cross-section on line 3 of Fig. 1, showing the construction of the device for riveting the hangers onto the cable; Fig. 4, a sectional view on line 4. of Fig. 3; Fig. 5, a sectional plan View on line 5 of Fig. 3; Fig. 6, a face view on line 6 of Fig. 3 of the stop to preventthe rivetingdevice from tipping; Fig. 7, a section on line 7 of Fig. 1, showing the device for marking off the points on the cable at which it is desired to secure the hangers. Fig. 8 is a section on line 8 of Fig. 1, showing the construction of the pulleys through which the cable runs in order to hold it straight while passing through the machine; Fig. 9, a perspective View of one of the hangers before its attachment to the cable; Fig. 10, a View of hanger as it is attached to the cable.

The construction and operation of this improved machine for fastening on the hangers is substantially as follows:

A is the main framework of the machine, shown in the drawings as constructed of angleiron and having lengthwise across the top two channel-irons or tracks A to accommodate the hanger clam ping and riveting device. At the left-hand end of the framework, Fig. 1, is a framework B, detachably connected to the main framework A by means of hooks b, which engage in holes provided therefor in the channel-ways A and the hinged bracket 1), the lower end of said bracket being bifurcated and fitting over a screw in the end piece of the'main framework. This framework B carries two sets of guide-pulley brackets B and B each of which contains a stationary grooved pulley b and an adj ust-able grooved pulley b revolving on a sleeve :0, which fits in the upright yoke, the said pulley being held in position by the bolt- :r', which passes through slots in the yoke sides and through the sleeve 00 and is secured by nuts, and also two side adjustable rollers b and b respectively. The yoke in which is secured the pulley b and rollers 12 and?) is hinged at the point I) to a portion of the bracket and secured in position by the thumb-screw b These brackets are hinged for the purpose of facilitating the placing of the cable in place between the rollers and accommodating different sized cables, the object of said rollers being to keep the said cable straight while passing through the machine. Between the brackets B and B and secured to the framework 13 is a bracket B which carries in a lower yoke a small grooved pulley W. The upper yoke B carries a grooved markingwheel B which automatically adjusts itself to the diameter of the cable, and is held in close contact with said cable by the springs 5 the pulley being journaled in slots in the bracket 13. The circumference of pulley B may be any length that may be desired, and has at a point on its periphery a marker 19 which makes an imprint or mark on the cable at points equal to the distance it is desired to have between the hangers. The yoke b is also hinged on one side to the lower yoke and secured on the opposite side by a thumb-screw similar to and for the same purpose as the brackets B and 13*.

At the opposite end of the main framework A is another detachable framework C, attached by the hooks c and hinged bracket 0, that carries two sets of single yoke-pulley brackets O and C each of which carries two horizontal grooved pulleys c and c and one vertical grooved pulley 0 which guide the cable after leaving the hanger-rivetin g device. The pulleys c and c are made adjustable in slots 0 in the bracket to fit diiferent-sized cables. The detachable frames l3 and C are made to fit either end of the main frame A, so that they may be placed according to the direction in which the cable is being drawn.

D is the yoke of the riveting device, which hangs between the channel-irons A on the top of the main frame A, having rollers a, which run upon the edge of the channel-iron, facilitating the movement of the riveting device. Fulcrumed to a link CL, which in turn is pivoted to the yoke D, is a lever D, one end terminating in a handle outside of the machine, the opposite end being pivoted to a block D sliding in guideways D in the yoke D. Through the center of this block D and the bottom of the yoke passes a rod D, threaded at its lower end to receive a nut and jam nut d, which are adjusted tolimit the upward movement of the rod D". Between the block D and the bottom of the yoke D are two collars d and (1 each provided with a set-screw, the collar d being to limit the downward movement of the rod D, and the collar (1 to limit the downward movement of the block D to which is pivoted the lever D.

The upper end of rod D terminates in an eye which engages with the pivot-pin s of the jaws E and E. The jaws E and E are angular in shape, pivoted at their apex on the pivot s. The lower ends of said jaws are provided with friction-rollers s',which bear upon the block D and are provided with a flange 3 which fits in a groove (Z in the block D said groove and flange being for the purpose of preventing any side or twisting motion of the jaws. The upper ends of said jaws are semicircular and adapted when closed to cmbrace the cable R. The upper end of jawE is adapted to engage the head of the rivet r in the hanger R, as shown in Fig. 4. The jaw E is provided at its upper end with a die 6, adapted to receive the rivet r as it comes through the hole in the hanger R, and as the jaws advance still closer together to force it upward at right angles to its length, thereby preventing its withdrawal and securelylocking the hanger on the cable. The upper portions of the jaws E and E are held apart by springs G, secured to eachjaw below thepivot s and having a contracting tendency.

To prevent the lifting of the riveting device while being operated, a casting II is pivoted between the flanges of the yoke D at a point under the guides A and which carriesaroller H, which travels on the under side of the guide channel-irons A. This casting is held in the position shown in Fig. 3, which is the position it assumes when the machine is operated by a spring-catch 11 said catch being drawn out when it is desired to remove the riveting device until the casting H drops or swings downward from the pivot 7L.

The operation of the machine is as follows, to wit: The cable is run between the guidepulleys in brackets B, 13 and B at the left end of the machine, as shown in Fig. 1, and between the jaws E and E of the riveting device and out between the guide-pulleys at the right-hand end of the machine in the brackets C and all of said pulleys being for the purpose of keeping the cable straight while passing through the riveting device D. The pulley B as the cable is drawn through the machine by means of the marker 13 on its periphery and its close contact with the cable B through the action of the springs U, marks cit on the cable the distance it is desired to have between the hangers. Hangers are placed in the jaws of the riveting device, as shown in Fig. 3, with a rivet in place, the head of which rests against the jaw E. The operator having lever D in charge at the proper time, which is when a mark made by the marking -wheel B comes opposite the jaws, presses down on the said lever D, which raises the block D The spring on the jaws holding them open, this upward movement of the block D carries with it the jaws E and E and rod D until the nut (Z strikes against the yoke D. At the same time said nut cl strikes the yoke D the bottom of the hanger has come in contact with the under side of the cable. It will now be seen that the continued raising of the block D will spread the lower portion of the jaws E and E from their pivot s and close the upper portion, which embraces the cable R with the hanger R, forcing the rivet 0' through the lip of the hanger into the die 6, where it is turned at right angles to its length and securely holds the hanger around the cable. The operator then releases the lever, the spring forces the jaws apart, and the jaws E and E, block D and rod D" drop until the collar (1 comes in contact with the yoke D, or to the position ICS illustrated in Fig. 3, when a new hanger is placed in position and the above operation again takes place.

It will be seen that this riveting device may be used on the framework A without the end frames B and C for holding the cable straight and marking the distances oil": thereon for the hangers as, for instance, men may guide the cable straight and the hangers may be fastened on indiscriminately,or the distance may be marked by hand, without departing from the spirit of the invention.
